struct

Geode::VectorBase(T, N)

Inherits Geode::CommonVector < Geode::VectorOperations < Geode::VectorMatrices < Geode::VectorGeometry < Geode::VectorComparison < Indexable < Enumerable < Iterable < Struct < Value < Object

Base type for all vectors with a specific dimensionality.

T is the scalar type. N is a positive integer indicating the number of components.

Constructors

new(array : StaticArray(T, N))

Constructs the vector with pre-existing values.

Source
new(other : CommonVector(T, M)) forall M

Copies the contents of another vector.

Source
new

Constructs the vector by yielding for each component.

The value of each component should be returned from the block. The block will be given the index of each component as an argument.

Vector3(Int32).new { |i| i * 5 } # => (0, 5, 10)
Source
zero

Constructs a zero-vector.

Each component will have a scalar value equal to the type's'zero value. This is done by calling T.zero for each component. The type T must have a class method

Vector3(Float32).zero # => (0.0, 0.0, 0.0)
Source

Instance methods

map

Returns a new vector where components are mapped by the given block.

vector = Vector3.new(1, 2, 3)
vector.map { |v| v * 2 } # => (2, 4, 6)
Source
to_slice

Returns a slice that points to the components in this vector.

NOTE: The returned slice is only valid for the caller's scope and sub-calls. The slice points to memory on the stack, it will be invalid after the caller returns.

Source
to_unsafe

Returns a pointer to the data for this vector.

The components are tightly packed and ordered consecutively in memory.

NOTE: The returned pointer is only valid for the caller's scope and sub-calls. The pointer refers to memory on the stack, it will be invalid after the caller returns.

Source
unsafe_fetch(index : Int)

Retrieves the scalar value of the component at the given index, without checking size boundaries.

End-users should never invoke this method directly. Instead, methods like #[] and #[]? should be used.

This method should only be directly invoked if the index is certain to be in bounds.
